Check Digit Verification of cas no

The CAS Registry Mumber 82101-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,0 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82101-81:
(7*8)+(6*2)+(5*1)+(4*0)+(3*1)+(2*8)+(1*1)=93
93 % 10 = 3
So 82101-81-3 is a valid CAS Registry Number.
